7 Web Server Unit

The Web Server offers a unit-based approach to running the server.

7.1 Signature

(require web-server/web-server-sig)

web-server^ : signature

(serve) → (-> void)

Runs the server and returns a procedure that shuts down the server.

(serve-ports ip op) → void

ip : input-port?

op : output-port?

Serves a single connection represented by the ports ip and op.

7.2 Unit

(require web-server/web-server-unit)

web-server@ :  (unit/c (web-config^ tcp^)         (web-server^))

Uses the web-config^ to construct a dispatcher? function that sets up one virtual host dispatcher, for each virtual host in the web-config^, that sequences the following operations:

• Logs the incoming request with the given format to the given file

• Performs HTTP Basic Authentication with the given password file

• Allows the "/conf/refresh-passwords" URL to refresh the password file.

• Allows the "/conf/collect-garbage" URL to call the garbage collector.

• Allows the "/conf/refresh-servlets" URL to refresh the servlets cache.

• Execute servlets under the "/servlets/" URL in the given servlet root directory.

• Serves files under the "/" URL in the given htdocs directory.

Using this dispatcher?, it loads a dispatching server that provides serve and serve-ports functions that operate as expected.
